How To Fix RSRV073 - Compare sizes of P or Q and X or Y tables for characteristic &1

RSRV073 - Overview

• Message type: E = Error

• Message class: RSRV -

• Message number: 073

• Message text: Compare sizes of P or Q and X or Y tables for characteristic &1

Description
The number of entries in <AB>P</>, <AB>X</>, <AB>Q</>, and <AB>Y</>
tables from the characteristic are compared. However, you need the same
amount of entries at any time.
<AB>X</> and <AB>Y</> tables contain the master data information for
the characteristic with internal keys instead of characteristic values.
They are used in reporting. An inconsistency leads to incorrect numbers
in reporting: Missing entries operate like (invisible) filters. The
case of having more entries in the <AB>X</> than in the <AB>P</> table,
or having more entries in the <AB>Q</> than in the <AB>Y</> table,
should not occur and points to serious inconsistencies. Possible cause:
System error when deleting master data.
Note
It is possible, although unlikely, that this test finds no errors, even
though <AB>P</> and <AB>X</>, or <AB>Q</> and <AB>Y</> tables are
inconsistent to each other.
Repair
The <AB>X</> or <AB>Y</> tables are rebuilt in the repair mode. If
errors still exist after the repair, then this points to missing
entries in the <AB>SID</> tables for the navigation attributes for the
characteristic. If you want to check this, use the (elementary) tests.
Type-based initial values for the attribute
Initial values in the <AB>SID</>- and master data tables for a
characteristic.
