ATP Check: R/3 and APO

Hi All,

My Query related to an Earlier Post (GATP: Unable to check ATP (in GATP) when creating sales order in R/3).

I would like to change the settings for ATP Check from APO system to R/3, I.E, the ATP Check for Business Rule should be triggered in R/3 and not in APO.

In the earlier post, inputs were provided for the following:

- Activation of ATP in external system: this is done in SPRO in the data transfer section.

- Another common point is cheking rule: In SPRO see that your business event(SO) is enabled for ATP check.

As per my information, the 'ATP Check' tick is possible at the level of Checking Group and Schedule Line Category in R/3

Could someone please provide inputs as to where in SPRO can we check the above 2 points mentioned?

regards,

Sudhir
