SAP Note 28169 - F4: Standard search in the matchcode is not set

Symptom:

After pressing the button/icon "New search" in the restriction popup of the matchcode search, a new search method is chosen. However, this is not used as the standard search method when the matchcode help (matchcode ID) is next started.

Cause and prerequisites

A search method (ID) is only used as the standard when first starting the matchcode help, if it is set as the standard using the function "Define standard".
Note: if the module HELP_VALUES_GET_WITH_MACO is used in a user-defined F4 matchcode search, the note is valid up to Release 3.0F.

Solution

If you want to set a new search method as the standard, you must perform the function "Define standard". The respective button/icon appears on the right, next to the button/icon "New search".
Further actions:

Also check whether there are any inconsistent entries in table MCDEFID using Transaction SE16 or SE17 for displaying tables. Such entries have the value SPACE in the MCID field or they have values which do not exist anymore.

Where necessary, delete these entries with the procedure described below.
To avoid further inconsistencies, change line 85 in the Include LSHL2U10 - function module MATCHCODE_ID_SELECT - as shown below.
