Purchase Req user exit

[Former Member]

I am having difficulty entering a user exit, M06B0002, function EXIT_SAPLEBND_001 include ZXM06U13. It should allow me to set CEBAN-USRC1 a user field which would allow me to determine the release strategy using this as a classification.

The system works fine for user exit M06B0001 which allows the person in workflow responsible to be determined. But this does not allow me to manipulate field USRC1.

I have added the enhancement M06B0002 to project Z06B0001 which already contains M06B0001 and activated the enhancement. Include ZXM06U13 has been activated as well, yet a breakpoint in the code is not hit.

Any suggestions?

Check the function module ME_REL_STRATEGIE_EBAN (Line number 50). Put a break-point here and debug to see whether the enhancement is called. The enhancement is called only when there is an entry in DB table T16FG where FRGOT = 1 and FRGFG <> 'X'.

Interesting. Not only is the Function ME_REL_STRATEGIE_EBAN not hit but the calling function ME_REL_STRATEGY_REQUISITION is not hit either.

I put breakpoints at the beginning of both functions. Though function EXIT_SAPLMEREQ_005 include ZXM02U05 is hit in a breakpoint.

There is an entry in table T16FG where FRGOT = 1 and FRGFG = 'X'.

Is there something incorrect with enhancement or could it be that introducing two more classifications that have not been completely determined in all classifications?

Progress has been made. It has been suggested that I should use enhancement M06B0005. This does enter function module ME_REL_STRATEGIE_EBAN and does come up with the correct release strategy.

However, if I change key fields in the pruchase req document, which should force it to re-calculate the release strategy, it does not.

By debugging it enters function ME_REL_STRATEGIE_EBAN, but does not come up with a result.

Still in DEVL so no harm done.

The release strategies have been configured (in DEVL) the coding is in place, and the correct release codes are listed. I have even got the substitution to work. However, if I change the document type before saving, it fails to re-evaluate the new release strategy. Since this is a mistake that many users will make, I need to determine why this is so. Debugging has shown that it is re-determining personnel in ZXM06U12, but this would be after the strategy had been determined. ZXM02U05 verifies the customer fieldsand the flag EX_RECHECK_ITEM is being set. I have checked SAP Notes. Any ideas?

I have determined that I have not introduced any bugs. the same situation already exists in PROD. The Release Strategy is not re-determined when the requisition has been checked, the doc type changed and re-checked. However if the value is changed by one cent the release strategy is re-determined.

The workaround is to save the requisition in ME51N then to edit it in ME52N or to make a change in the value.
