How To Fix CNV_10020574 - Memory requirements cannot be calculated for table &1 for &2 &3

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 574

• Message text: Memory requirements cannot be calculated for table &1 for &2 &3

What causes this issue?

The system found that &V2& &V3& was stored for the org. determination
for table &V1& (possibly as a subpath). For this path, determination at
runtime has been defined. This means that relationship data is
determined at runtime and not uploaded from one of the object tables.
For this reason, it is not possible to calculate the storage
requirements for &V2& &V3&.

How to fix this error?

No action is required. Determination at runtime is normally used only in
exceptional cases and for special determination paths. The memory
requirements should be small. Probably it is not even possible to change
the determination type.
