batch derivation problems

[Former Member]

Hello,

I have problems with the set up of a derivation process, I have checked the common link http://help.sap.com/saphelp_erp60_sp/helpdata/en/25/28428b4f7811d18a150000e816ae6e/frameset.htm - but I still got problems to make it or to undestand how to set it up. What we want to do is: we have a characteristic A in the batch class1 of raw material X evaluated in an inspection process. This value has to be transferred to the batch of the product Y - batch class2 (includes also characteristic A). the derivation should happen when the inspection lot of product Y gets the usage decision. Characteristic A is not used for this inspection lot, only the value should be transferred from batch1 of used raw material X to batch2 of product Y.

What are the settings I need to get this running? Please a little more details since I struggle to understand that SAP help document! Batch derivation is active (DVSP). In DVC8 we have a record for event 100 (usage decision) for the product Y.

the record is maintained as follows: recipient: product Y, sender material X , the characteristic is characteristic A.

When I do the usage decision for the product inspection lot, only the batch characteristics used in this inspection lot get evaluated. The used batch of the raw material is defined in the material list of the production order and was also used as consumed batch in the order confirmation process.

What else do I need to get the process running? What is wrong with my idea? Where should I check what? Any ideas?

Thanks a lot

Kurt

Hi,

Just a thought:

Try running the derivation for same batch classes first. I have configured BD recently but have not tried for different classes.

The check list is given below, hope it helps to track the error:

1. OMBB - BaWU sync. posting ticked (this is mandatory).

2. Condition tables for receiver and sender batches

3. Access sequence for sender and receiver.

4. Strategy types and search procedures for sender and receiver.

5. Condition Record in DVR1 and DVS1.

Check & Revert.

Regards,

Rohit.

Added: It works for different classes. I have checked it. Please check other thingst.

Yep, it get's crazy now. I tried using the same class for product y and raw material x. First I forgot to maintain the material specification for the product - here the system told me during UD for the inspection lot 'pull process starts' - and the value of characteristic A taken from raw material batch appeared on product batch - just the value of characteristic B (from inspection lot for product batch) did not appear in the new product batch.

Next I maintained the material specification for the product and was hoping the first step would run now. It looked nice until the same message appeared during UD for the product lot. But now only the value for the characteristic B which was inspected appears in the product batch - deviation of characteristic values A from raw material lot did nto happen.

What's wrong?

Hello Rohit,

finally I got it working using different classes also.

thanks for the hints, it was a good starting point.

Hi  Kurt Wichert,

We are facing the same issue in batch derivation with different classes please share the solution you made to fix it.

Warm Regards,
