Table: TCUCH

Batch Number Assignment

Creating Batch:

In batch master record maintenance(Batch Management)

In goods movement(Inventory Management)

In purchase orders(Purchasing)

In production/process orders(Production)

In results recording(Quality Management)

Automatic/Manually: Control in customizing OCHA

Batch number assignment: Internal/External

User-exit:

Automatic: EXIT_SAPLV01Z_001/EXIT_SAPLV01_Z_002

Manual: EXIT_SAPLV01Z_003/EXIT_SAPLV01Z_004, EXIT_SAPLV01Z_013 and EXIT_SAPMM07M_003 (inventory management, only for new batches) can be used to change the master data of a batch.

Common information:

Since release 470 definition for batch number assignment is transported via table TCUBN
(before it was part of table TCUCH!)

Batch numbering without gaps is impossible (for explanation see note , item 6)

Assign the same batch number for more than one goods receipt:
Use exit
EXIT_SAPMM07M_010 (if goods movements are posted)
Use modification according to note for VB_CREATE_BATCH (relevant e.g. for REM - release >=470).
[The modification is replaced by BADI mentioned in note ]

Functionmodules:
VB_NEXT_BATCH_NUMBER (internal batch numbering)
VB_CHECK_BATCH_NUMBER (external batch numbering)

Batch Classification

Characteristic Types in Batch Classification:

User-defined characteristics: Characteristics that do not reference table fields

Object Characteristics: Characteristics that refer to table fields.

Standard characteristics: These are Batch Management characteristics that are delivered in the SAP standard system. They are reference characteristics from tables MCHA and MCH1. All standard characteristics can be found in F4 help by specifying LOBM_*. You are normally not allowed to make changes to standard characteristics in the characteristic master record.

One batch class per material (note ), but batch classification can be assigned to multiple objects (check transaction O1CL)

Accordingto batch level class type is determined (material/client: 023, plant: 022)

Batch classification can be maintained in batch master transactions, and in several applications (goods movements, orders, process messages)

Update standard Features: BMSM

Classifying batch during goods movement: OMJJ

Tables:

Classification is called in: VB_CREATE_BATCH and VB_CHANGE_BATCH

Classification FM: CLFM_OBJECT_CLASSIFICATION

User Exits to fill free characteristics:

EXIT_SAPLV01Z_014(not called in MB* transactions, but in MIGO!)

EXIT_SAPMM07M_004(called in inventory management transactions and when posting goods movements via MB_CREATE_GOODS_MOVEMENT)

Reports:

Integrity Check for Batch Classification – BMCC

RCCLZUOB(checks whether object exists for classification entry in table INOB - e.g. entry for temporary document number)

RCCLINOBDEL(deletes multiple INOB entries for one object)

RVBCOR16(checks the customizing of batches concerning classification)

Archiving Object MM_SPSTOCK

Pay attention on the indicator:

‘Only consider batch stock records; batch master record will not be deleted’

Batch Status Management

Batch status management is activated via transaction OMCT.

Batch status can be changed in batch master transaction and via usage decision (transaction QA11).

There are two options to prevent restricted batches from being selected within batch determination:
- insert characteristic LOBM_ZUSTD in batch class and selection class
- work with dynamic ATP check (scope of check – OVZ9)

Functionmodules:
VB_CHANGE_BATCH_STATUS
VB_CHANGE_BATCH_STATUS_STOCKS
VB_BATCH_DEFAULT_STATUS

Exit:EXIT_SAPLV01D_001 (determine initial status of batch)

Fields: TCUCH-KZDZV T001W-CHAZV (batch level on plant)

Batch Determination

Batch Search Strategy Customizing

Five Scenarios

Inventory Management

Production order

Process order

Sales and distribution

Warehouse Management

Five scenarios have similar steps to define the batch search strategy.

Five Steps in OCHA:

Define Condition tables : Condition tables are combinations of fields that form the key of the batch search strategy.

Define Access Sequences: The order in which the system accesses condition tables during batch determination.

Define Strategy Types: The default values used when a strategy record is created.

DefineSearch Procedure: The order in which you assign the strategy types is the order in which the system searches for strategy records.

Search Procedure allocation and check activation: Allocate the search procedures to the application-specific parameters. Batch determination becomes active as soon as you make the allocation.

Selection Class

Define in CL01/CL02/CL03

With the help of these selection classes, you define according to which criteria, that is, using which characteristics, batches are to be selected

All characteristics (this applies to standard characteristics as well as to user-defined characteristics) you want to use for selection must also be contained in the batch class. Characteristics LOBM_RLZ and LOBM_LFDAT are an exception; they can be used for selection but not for classification

To copy the characteristics from client 000 to your logon client, use report RMMCCH01.

Sort Rule

Define in CU70/CU71/CU72

With the help of sort rules, you define according to which criteria, that is using which characteristics batchesare to be sorted.

All characteristics (this applies to standard characteristics as well as to user-defined characteristics) you want to use for selection must also be contained in the batch class. Characteristics LOBM_MENGE and LOBM_LGORT are an exception; they can be used for selection but NOT for classification.

Batch determination is used for goods issues and stock transfers in SAP warehouse management systems.

Batches to be picked are transmitted to warehouse management (batch determination takes place in upstream applications).

Batches are determined from warehouse management (Batch determination in warehouse management).

Batch Information Cockpit

Basics

Transaction BMBC functions as single point of entry for batch information and comprises severaltransactions:

MSC2N, MSC3N, MB56, MMBE, CO09, CL30N, MB5C

Selections

Note

Selection Result

SelectionResults: Batches

Here, the main focus is on the selected batches. The batches are displayed in accordance with the batch definition level.

SelectionResults: Stock

Here, the main focus is on the stock situation of the selected batches.

Following stock tables are read:

–MCHB

(free stock, special stock indicator = blank)

–MKOL

(Special stocks from vendor, special stock indicator = k)

–MSKA

(sales order stock, special stock indicator = E)

–MSKU

(special stocks with customer, special stock indicator = V and W)

–MSLB

(special stocks with vendor, special stock indicator = O)

–MSPR

(project stock, special stock indicator Q)

Restrictions

Nmber of batches 50 but only 20 displayed.

System read all batches of material A, for example 70. User Parameter said maximum 50 batches, so system take the first 50 and send message ‘more then 50 batches found’

Next step take 50 batches and check if they fit the selection criteria, so for example only 30 batches are displayed customer

In the selection result of the Batch Information Cockpit you can display in all 50 characteristics, but it is limited to 20 for character types, 20 for numeric types and 10 for date and time types.

Old batches are note displayed after upgrade to EHP5, reason is new added field BATCH_TYPE, noteprovide a report to update the old

Batch Derivation

Basic Information

Batch Derivation is based on batchwhere-usedlist (table CHVW and CHVW_PRE areread).

Batch Derivation is triggered by certaine vents (transaction DVC8)

No batch derivation for stock transfers (use exit EXIT_SAPMM07M_004 instead)

Derivation Mode:

Pull Derivation (1 Receiver, n Sender)
The derivation is triggered from a transaction that affects the product. Here, data from various senders can be collected, cumulated, and calculated. Within a derivation according to the pull principle, there can only be one receiver, but there can be several senders (example usage: pick and pack for pharmaceutical products).

Push Derivation (n Receiver, 1 Sender)
Within a derivation according to the push principle, there can only be one sender and several receivers. This derivation is started from a transaction that affects the component batch. Here, data from a sender batch can be derived onto several receiver batches (Example usage: Filling bulk batches in the Chemicals industry).

Customizing

Derivation events (DVC8)

Determine at which time a derivation should happen and which rule should be used.

Static or dynamic derivation
- Static Derivation: For a static derivation, the attributes determined for the sender batch(es) are transferred to the receiver batch(es).
- Static derivation is recommended if a batch is newly created or changed and the values in the receiver batch(es) should be filled with the attributes from the sender batch(es).
- Dynamic derivation: For a dynamic derivation, no attributes are transferred to the receiver batch(es), in other words, the derivation is simulated and the values are merely displayed. The derivation is saved, but the receiver batch(es) are not automatically changed.
- Dynamic derivation is used when the receiver batch must/should not be changed and the sender values should be used as the basis for a user decision.
