¿Qué causa este problema?

In the current procedure call expression, you have defined an invalid
mapping between the parameters of the expression and of the called
method or function module. Two or more Exporting / Changing / Returning
/ Tables parameters are mapped to the same BRFplus table data object
&v1&. This is not allowed for reasons that can best be explained by an
example:
Assume you have defined a parameter mapping like this:
Parameter,,BRFplus Data Object,,Move Type
ET_PARTNER_H,,DO_TBL_BUSPARTNER,,MOVE-CORRESPONDING (TMC)
ET_PARTNER_I,,DO_TBL_BUSPARTNER,,MOVE-VALUE (TMV)
Once the called procedure has been executed and is about to return
control to the calling expression, both parameters are filled with the
appropriate values. Since it is impossible for the procedure call
expression to know how the parameters have been processed by the called
method or function module, it could happen that the two parameters
return the same table object with a different number of records. In such
a situation, it would be impossible for the system to decide how to
proceed with the concurrent states of the table object.

Respuesta del sistema

The expression cannot be activated.

¿Cómo arreglar este error?

Depending on your original intention, proceed as follows to solve this
problem:
Table data object has been intentionally passed twice to the called
method or function module: Create a copy of table &v1& and use it for
the second parameter. After the procedure call expression has been
executed, merge the contents of the two tables with the help of an
additional loop expression.
Table data object has been passed twice by mistake: Create a second
table data object to be passed as the second parameter.
