Administrator privileges are required to configure the
BOM Comparison function! |
|
When initiating a BOM Comparison, you have a number
of choices as to how the comparison will be run and how the results will
be presented. You may:
- Enter the parameters which will control the comparison when the function
is started, or
- Use a LogiView procedure to control the function operation and results.
|
|
Parameter Input at Function Initiation
|
|
A BOM Comparison is started by the xdiff_start_mmn userexit.
That exit can be called with the following parameters: |
|
Parameter |
Function |
Default |
{/OUT={FILE| TABLE}} |
Output written to file or table |
FILE |
{/DEP=xx} |
Depth limitation |
15 levels |
{/ET=ETNAME} |
Name of decision table to use. |
|
/VIE=SICHT |
Name of the view (see ER Model, here ART) |
|
{/WDG=ENTNAM WDGNAME} |
Name of entity and widget that are to be opened in order
to save the results |
EDB-DIFF EDB-DIF-SLI |
{/NOKEYF} |
Enable comparison for items with different item numbers. |
Only compare when item numbers are the same. |
|
|
To start the BOM Comparison with the desired parameters, they
must be entered in the Selection Data mask. |
|
The DIF/DIF_DT procedure is used to control which fields
in the comparison string are displayed. If there is no difference in one
of the selected fields, then that portion of the comparison string remains
empty. |
 |
Call the DIF/DIF_DT procedure using the function in the
list inside the Decision Table/Procedures Logic Model mask. |
|
 |
|
The
mask is opened. |
|
 |
|
The fields to be compared must be declared as local
logic model variables. The variable types must agree with the types of
the fields to be compared! |
|
Example: |
|
Variable Name |
|
Table Access |
DIF_QUA_A( Quantity Comparison) |
|
"T_MASTER_STR.QUANTITY", "T_MASTER_STR.C_ID_2" =DIF_CID_SON_A&
"T_MASTER_STR.C_ID_1" =DIF_CID_DAD_A& "T_MASTER_STR.POS_NO" =DIF_POS_NO |
DIF_QUA_B |
|
"T_MASTER_STR.QUANTITY", "T_MASTER_STR.C_ID_2" =DIF_CID_SON_B&
"T_MASTER_STR.C_ID_1" =DIF_CID_DAD_B& "T_MASTER_STR.POS_NO" =DIF_POS_NO |
|
|
Type agreement is also required when creating comparison
strings in the decision table! |
|
In addition, global system variables are required |
