If else condition not working as exoected for multiple line items

Hi All,

If else condition is used for a target field at line item level, Condition checks a field at header level in source structure based on that a constant value is mapped to target.

For single line item the logic works but for multiple line items the target field is not getting populated.

I tried the node functions, remove context, split by value by nothing works.

Also tried using fixed value mapping but same issue exist.

Please suggest

Thanks
