Rule Based ATP- Error in calling up function 'BAPI_APOATP_CHECK' in APO ser

[Former Member]

Hi Experts

I hae configured Rule Based ATP with Multi-Level ATP check. I have completed all configuration required for Rule Based ATP but still facing an error

" Error in calling up function 'BAPI_APOATP_CHECK' in APO server 'SC5CLNT001': Check instructions 30 / A does not exist for locat"

Have any of you ever encountered this error?

Dear Sushovan,

Most likely cause of the above error is a missing requirement class in R/3 and missing Check mode in APO for material and plant combination.

Please read the F1-Help for field check mode in APO:

"Together with the business event, the check mode derived from the product master defines the type and scope of the checks carried out. It also controls forecast consumption.

SD (R/3) uses the requirement class of the requirement as check mode. As of R/3 Plugin 2000.1, the requirement class is transferred (via the strategy group in the material master) to the location-specific APO product master (ATP tab page). In the process, no plausibility check is carried out. For this reason, you should not enter any other check mode in the product master. (The check mode in the product master must agree with the requirement class from the R/3 system.)"

So please create for your material in corresponding plant the requirement class ' 030' assigned to the strategy group in MRP3 in R/3 and the same in the check mode field in //mat1 in APO.

Afterwards the gatp check will find the check mode and business event (check instructions) and the error will be not appear again.

Regards,

Tibor
