MEQUERY1 - Enhancement to Document Overview ME21N/ME51N
Fill RESBD Structure from EBP Component Structure ABAP Short ReferenceThis documentation is copyright by SAP AG.
This enhancement enables you to:
- Execute selection variants with your own queries
- Override or remove standard queries
- Define your own selection variants
- Define your own display variants for your own selection variants
Using this enhancement, you can create your own selection variants for the document overview and include
them in the selection menu for the selection variants. You can also use these selection variants to
execute your own previously generated queries and provide existing standard selections with your own variants. Lastly, you can assign your own display variants to each selection variant.
Function exit 001:
EXIT_SAPLMEQUERY_001
In this function module, you can assign an ID in the ClassID field and a name in the Label field.
The new ID you assign must lie within the customer name range in order to avoid conflicts with existing
IDs. For this reason, use a 'Z' as the first letter of the ID. This ID is needed to access the variant created.
The name is the description under which the variant is shown in the selection menu.
Note
Please note that the name is displayed on the user interface and is thus language-dependent.
It is also possible to remove the standard variants. All variants displayed are stored in the table META_TABLE.
The ClassIDs of the standard system are defined in the type group MMPUR.
Function exit 002 :
EXIT_SAPLMEQUERY_002
In this function module, you can define the relevant parameters needed for your selection variant. This function module is used for each selection variant that is used in the selection menu. On the basis of the ClassID, you can change the following parameters:
-
ch_queryname: Name of the query that must first be generated using transaction SQ01, or use of standard SAP queries.
In order to be able to use the standard SAP queries, it is essential to set up the global work area using the variables ch_workspace. - ch_usergroup: Name of user group to which the query is assigned.
-
ch_variant: Name of variant with which the query is to be started.
If no variant is desired, ' ' can also be passed on. -
ch_handle: The display variants of the selection are to be found here.
You can control the representation of the various selections in the document overview via different display variants. To define different display variants for different selections, you need a handle. When executing the selection variant, you can then either choose from all display variants stored unter the handle that has been passed on or set a display variant that is then used for each call.
The handles already assigned in the standard system are 0001 for purchase orders and 0002 for requisitions. You can assign your own handles from 9000 upwards. -
ch_workspace: If an X is passed on here, the
global work area is used and the specified query sought there. If the setting is ' ', the query is sought in the local work area. As a rule, only SAP queries are available in the global work area.
Example data is stored for each function exit. This can be invoked by displaying the components for the enhancement and then displaying the function code for the desired function module.
Purchase order (transactions ME21N / ME22N / ME23N)
If you wish to use the Drag&Drop functionality with the shopping basket, or include documents shown in the document overview in the purchase order (using the Adopt @14@ icon or by double-clicking on the document number), the field selection for the query must contain the following fields:
- EKKO-BSTYP : Document category
- EKKO-EBELN : Document number
- EKPO-EBELP : Document item
If you do not include these fields in the selection, it is not possible to adopt the document in the purchase order.
Purchase requisition (transactions ME51N / ME52N / ME53N)
If you wish to use the Drag&Drop functionality with the shopping basket, or include documents shown in the document overview in the purchase requisition (using the Adopt @14@ icon or by double-clicking on the document number), the field selection for the query must contain the following fields:
- EBAN-BANFN : Requisition number
- EBAN-BNFPO : Requisition item
You must also define these fields as key fields.
