How To Fix BTP_DL088 - Combining of '&1' with '&2' is not possible

SAP Error Message - Details

• Message type: E = Error

• Message class: BTP_DL -

• Message number: 088

• Message text: Combining of '&1' with '&2' is not possible

What causes this issue?

Combining compatibility of solutions is maintained with so-called
configuration sets. A configuration set specifies if solutions can be
combined into one single step in the project execution plan. Then, for
all the combined solutions in a step one single conversion package can
be created. Configuration sets are delivered by SAP with the portfolio
content of SAP LT and are not visible on the user interface.
For solutions '&V1&' (version &V3&) and '&V2&' (version &V4&) there
cannot be located any configuration set in the SAP LT portfolio. Hence,
these solutions cannot be combined into one single step.
