Issue while loading Data from BW to BPC

Hello Experts,

I am facing a weird issue while loading data from BW mini cube to BPC for consolidation

we have one mini cube in BW which basically stores data from all sources (ECC & Flat file).

I am trying to load above combination of data from Mini Cube to BPC & I am getting this error.

I am not able to understand why system is mapping is doing so. For the same combination for the entity ESA, the data gets properly loaded but for the entity EUK, i am getting this error and that too for this GL.

My transformation file looks like this:

Regards,

Rahul
