How to fix this error?

Restart allocation rule generation.
If the error occurs again, check whether a selection variant exists for
the key figure category you used. You can create a selection variant as
follows:
Automatically for the key figure category:
In the Allocation screen, choose Allocation rule -> Create selection
variant. Then enter one or more key figure categories and start the
program.
Manually:
Define the <DS:SIMG.W_ZF_VK_0463.SIMG_OAUF>selection variants</> in
Customizing for the allocation rule.
If the error still occurs after you have created a selection variant,
contact your system administrator.
Note for the system administrator:
A dynamic ASSIGN command could not be executed in the FORM routine
'Determine_RIS_Data'. It is possible that include TMCWWTOP, which is
required by function module 'MCW_GET_VALUES_FROM_INFOSTRUCT' for
evaluating the returned data, is empty. Check whether include TMCWWTOP
contains the program code for defining internal tables.
