SAP Error Message - Details

• Message type: E = Error

• Message class: RSCV - Analysis of BW objects (InfoCubes...)

• Message number: 337

• Message text: Master data '&1' in table &2 (characteristic &3) contains small letters

What causes this issue?

The master data with characteristic value '&v1&' contains small
letters. Since the characteristic value is used in the master data as a
key, this will cause problems, since capital and small letters
represent different keys on the database.

System Response

Posted transaction data for this characteristic value is possibly not
evaluated in reporting.
For example, transaction data with the name 'SMITH' and 'Smith' has
been posted. A query is now executed and thus limited to the name
'SMITH', ONLY the transaction data posted for this characteristic value
is selected. On the other hand, summarized using the name, ALL posted
transaction data is used.

How to fix this error?

You can correct all keys (convert into capitals) by starting the
correction in the entry screen with 'Repair error'. Consequently, all
dependent objects are corrected. It is possible that this can last a
long time, since a characteristic can, for example, be used in a great
many InfoCubes.
