[Feat]: Update table `TVARVC`

[Tom Schmelzer]

TVARVC - Table of Variant Variables (Client-Specific)

Some programs are only supporting the selection variable T (T: Table Variable from TVARVC) when saving a variant for given programs.

For those kind of programs following TVARVC-Variables should be implemented in the system.

For example:

• Z_FI_CURRENT_YEAR
• Z_FI_CURRENT_MONTH
• U_FI_PREVIOUS_YEAR
• Z_FI_PREVIOUS_MONTH

These variables can be used in the variant selection as followed.

Since the variables in the table are static entries, they should be updated periodically using the following program.

REPORT zfi_update_tvarvc.

DATA: previous_month TYPE syst_datum.
CALL FUNCTION 'OIL_GET_PREV_MONTH'
  EXPORTING
    i_date = sy-datum
  IMPORTING
    e_date = previous_month.

SELECT SINGLE * FROM tvarvc WHERE name = 'Z_FI_CURRENT_YEAR' AND type = 'P' INTO @DATA(tvarvc_line).
UPDATE tvarvc FROM @( VALUE #(  BASE tvarvc_line low = sy-datum+0(4) ) ).
CLEAR tvarvc_line.

SELECT SINGLE * FROM tvarvc WHERE name = 'Z_FI_CURRENT_MONTH' AND type = 'P' INTO @tvarvc_line.
UPDATE tvarvc FROM @( VALUE #( BASE tvarvc_line low = sy-datum+4(2) ) ).
CLEAR tvarvc_line.

SELECT SINGLE * FROM tvarvc WHERE name = 'Z_FI_YEAR_OF_PREVIOUS_MONTH' AND type = 'P' INTO @tvarvc_line.
UPDATE tvarvc FROM @( VALUE #(  BASE tvarvc_line low = previous_month+0(4) ) ).
CLEAR tvarvc_line.

SELECT SINGLE * FROM tvarvc WHERE name = 'Z_FI_PREVIOUS_MONTH' AND type = 'P' INTO @tvarvc_line.
UPDATE tvarvc FROM @( VALUE #( BASE tvarvc_line low = previous_month+4(2) ) ).
CLEAR tvarvc_line.

Further variables can easily be added using following syntax:

SELECT SINGLE * FROM tvarvc WHERE name = 'variable_name' AND type = 'P' INTO @tvarvc_line.
UPDATE tvarvc FROM @( VALUE #( BASE tvarvc_line low = xxx ) ).

Warning: Please make sure to maintain the variables in transaction STVARV in each system.
