Data Migration Cockpit Master Recipe template uses non-standard field codes

[Chequebookgerry]

With all the other DMC templates, the technical field name used can be found in the relevant table (even if you have to hunt a bit for the table).  They are all there.  However, for this one pack, they are very different.  For example, for the Receipe Group, the field in the pack is MASTERRECIPEGROUP and not PLNNR in table PLKO, PLPO, etc.  When the data was originally loaded, a custom template was used (which in itself is odd, as it is the only one) which I have.  This contains the real codes, so for example PLNNR is used.  

So, has anyone actually used this standard Master Recipe template and, if so, did it work fine or was a huge amount of mapping needed?

Thanks.
