Error in calling up function 'BAPI_APOATP_CHECK'

[Former Member]

Dear Experts,

I'm encountering the error Error in calling up function 'BAPI_APOATP_CHECK' in APO server 'SXXCLNT100': Access via 'NULL'object reference not possible while performing the ATP check. However I'm getting this error for some materials. Has anyone of you encountered similar issue? Please suggest.

Thanks,

Krishna

Hi,

Is your APO system connected to ECC ?

You can check using T code SM59.

It means that your material in the integration model of ATP check but ECC system cannot connect to APO.

Hi,

The FM AVAILABILITY_CHECK calls BAPI_APOATP_CHECK as APO side and many reasons are there to show this error while doing ATP Check or saving sales order.It may sometime for temporary reason due to CIF queue where sales order might got struck.

As in your case it says ""Access via 'NULL'object reference not possible"" for few materials.Please check the material master and product master in ECC and APO system respectively along with CIF stuff.

Thanks,
