You want to display accounting documents with Transaction FB03 "Display Document". Accessing the accounting documents takes extremely long. The problem is due to a program error; A database index is missing.
You can further improve the performance by creating an additional database index that supports this access. Since this index is only relevant under special conditions as of a certain table size, it is not delivered in the standard system. If you want to further improve the access performance to accounting documents, proceed as follows:
Call up Transaction SE11.
Enter table FILCA.
Choose "Display".
Choose "Indexes".
Choose "Create"
Enter an index ID (for example, Z01).
Enter a short description (for example, Additional index AC).
Select the Non-unique index option.
Enter the following field names:
AWTYP
AWORG
REFDOCNR
LOGSYS
ROBUKRS
Choose "Save".
Activate the newly created index.
