Stock Transfer with RB-ATP (gATP) not working

Hello All,

I am trying to get gATP to create a stock transfer order (or STR) in ERP using PP/DS functionality as described in SAPHelp link below:

SAP Library - Rules-Based Availability Check

I have performed the following steps:

1. Created transportation lanes with means of transport
2. Set PP/DS horizon on product master to 30 Days
3. Set PP Planning Procedure to 5  on product master
4. Created scheduling horizon for the conversion of ATP tree structures (Set to 30 Days)
5. Defined the production type Standard in the check mode
6. Activated the rules-based ATP check in the check instructions. A call to PP/DS is not specified– neither in the check instructions nor in the location determination activity of the relevant rule – at least as far as I can tell…
7. Created a rule and assigned a location determination procedure with a fan-shaped structure type to this rule
8. Assigned a location determination activity to the location determination procedure – Stock Transfer Indicator is set.

Please note, at the moment we are not using PP/DS for anything else yet, so no other PP/DS specific configuration has been performed. Also, no CIF specific config from APO back to ERP.

During sales order entry, RB-ATP in APO is triggered, and correct rule etc. is determined.

Requirement date is 10 days from today to fall inside planning horizon.

After saving the order, no STO or STR is created in ERP or in APO.

No requirement visible in APO via transaction /SAPAPO/RRP3

Any idea where I am going wrong?

This is what my transportation lanes looks like:

This is my check instructions:

Any help will be appreciated!
