&1 &2 has maximum target card. N, which is not allowed for intervals
Help Document

Diagnosis

The system found that the maximum target cardinality determined for is N, which is not allowed for intervals (for technical reasons).

Note: The following example shows why a target cardinality of N is not allowed.
Example: Purchasing organizations 0001 to 0010 are assigned to plant 0001. Purchasing organizations 0002 to 0006 are additionally assigned to plant 0002, and purchasing organizations 0007 to 0009 are additionally assigned to plant 0003. The interval table would then look as follows:

DTVAL_S_HIGH DTVAL_S_LOW DTVAL_T
0006 0002 0002
0009 0007 0003
0010 0001 0001

To find the related plants for purchasing organization 0005, the program would have to read records 1 and 3. However another relevant record might occur at any other place in the table, which means that the table must be processed completely every time it is accessed, an which in turn would result in serious performance issues. If, however, there is exactly one target determination value, only a single access is required.

System Response

If necessary, determine the system cardinality of . If the target cardinality in this case is N as well, creation of intervals for is not possible.
