User Formula not working in TAB Account Rule

Summary:

Our customer uses Oracle Self-Service Procurement to create and manage their purchase requisitions.

Regarding the charge account, the goal is to automatically derive the full account combination.

Follow the requirement to derive the segments account and project:

Project: Must consider the project code filled in the field “PO Distribution Attribute1” in the requisition distribution. Please note this DFF shows a code considering the concatenation of the project synthetic value (first 3 digits) + project analytical value (next 8 digits). So, this rule must be based on the project analytical value (8 digits).

Account: Must be derived based on the item purchasing category and the project synthetic value (first 3 digits in the DFF).
