FCCS ODR Issue – Dynamic Block Creation for Reverse ICP Cash Flow Entries

We are implementing an FCCS cash flow movement logic using ODR where data entered in one Entity/ICP combination needs to automatically create a reversing entry in the corresponding ICP entity.

Example:

Source:
acc123 -> Ent1 -> ICP_Ent2

Expected Reverse Entry:
acc789/acc987 -> Ent2 -> ICP_Ent1

Current ODR logic derives the target Entity and ICP dynamically using the source Entity and Intercompany members. The calculation works correctly if a data block already exists on the target intersection (for example, when we manually enter 0 or some value in acc987). However, if no block exists, the reverse entry is not getting created.
