GATP , product availability check error

[Former Member]

Hello all

I have a APO product with check mode, ATP group . The ATP customizing is correct inmy understanding and the ATP simulation in APO gives correct results. However when I create a sales order in R3 , it results in an error:

Error in calling up function 'BAPI_APOATP_CHECK' in APO server 'APOCLNT800': Screen output without connection to user.

Message no. AG023

Diagnosis

A system error or communication error occurred while calling up a

function in the APO server.

Thanks in advance and any help is appreciated

Hi,

The problem is with the userid of RFC. In RFC Connection from R/3 to APO the user id should be a dialogue user. which is not at present in your system.

Make it a dialogue user, and the error will go away.

Please follow the link

Hi,

Just wanted to clear one point here :

In RFC Connection from R/3 to APO the user id should be a dialogue user " in case of ATP check from R/3 to APO"

if ATP check is not done in APO then the RFC user id can be other than dialogue user. example APO is used for SNP/ DP and Plants, materials, sales orders, stock etc are cifed.

Thanks,
