Key field WGLIF is not supported. LTMOM / LTMC Migration tools for MM Conditions.

Problem: Using we have this error CND_GEN_MIGRATION 004 Key field LIFNR is not supported / Key field WGLIF is not supported because we are using a standard field for conditions but this is not included in the combinations of key fields for price conditions in OSS-Note 2332748.

Solution: After a debugging and I found this 2 oss-notes:

2928354 - The provided key fields are not supported by the condition type XXX

2992615 - Migration of fields not listed in Supported Key Combinations in S4Hana On-Premise System

Then I added with SM30 in view VCND_MIG_SAPFLDS a row for the fieldname WGLIF (or LIFNR,....). 

And also you need to add I also need registers for field KFRST in any case in the staging case for Conditions Keys.
