How To Fix FDT_EXPRESSIONS263 - Decision table does not fulfill the criteria for completeness check

SAP Error Message - Details

• Message type: E = Error

• Message class: FDT_EXPRESSIONS - Formula & Derivation Tool: Expressions

• Message number: 263

• Message text: Decision table does not fulfill the criteria for completeness check

What causes this issue?

You have tried to perform a completeness check for the current decision
table. However, the pre-analysis of the table has detected that one or
more of the prerequisites are not met by this table.
The completeness check is a content-based check that analyzes the table
cell content for formal correctness. This is only possible if several
prerequisites are fulfilled. Here are some examples:
In the condition columns, only number, text, and boolean data objects
are checked.
Text data objects assigned to the condition columns have a list of
domain values defined.
There is no row where all cells contain an unspecific value.
The table has no more than 10000 rows.

System Response

The completeness check cannot be performed for the current decision
table.

How to fix this error?

Check if there are data objects used that can be enhanced by a list of
domain values.
Should the table violate any of the other prerequisites listed above,
then there is most likely no way to adapt the table such that the
prerequisites are fulfilled. In that case, we recommend that you
thoroughly analyze the condition rows on a manual basis.
