Subcontract Reservations in RESB Table

Hi Experts,
I have reservations of child component in RESB table which are resulted from the parent component in Subcontracting Scheduling Agreement.
All Delivery Schedules lines are completed (GR Made.) Still reservations exist for child component.
Please suggest how to remove these reservations from RESB Table.
Regards,
Shravan.

There is only one solution in this case if all efforts fail.
You have to write an ABAP code which will flag the Final issue indicator in RESB table for perticular reservation. In this case you have to flag exact reservations and close that chapter not to be opened again. in future.

How can we improve the performance while fetching data from RESB table.

Hi All,
Can any bosy suggest me the right way to improve the performance while fetching data from RESB table. Below is the select statement.
SELECT aufnr posnr roms1 roanz
    INTO (itab-aufnr, itab-pposnr, itab-roms1, itab-roanz)
    FROM resb
    WHERE kdauf = p_vbeln
    AND   ablad = itab-sposnr+2.
Here I am using 'KDAUF' & 'ABLAD' in condition. Can we use secondary index for improving the performance in this case.
Regards,
Himanshu

Hi ,
Declare intenal table with only those four fields.
and try the beloe code....
SELECT aufnr posnr roms1 roanz
INTO table itab
FROM resb
WHERE kdauf = p_vbeln
AND ablad = itab-sposnr+2.
yes, you can also use secondary index for improving the performance in this case.

Error on RESB table changing planning order using BAPI_PRODORD_CHANGE

Hallo.
In my custom program ZINTERFACE_ORDER, I use BAPI 'BAPI_PRODORD_CHANGE' to change multiple production order (quantity / start date/ end date).
CALL FUNCTION 'BAPI_PRODORD_CHANGE'
     EXPORTING
number       = wk_ordine
orderdata    = wk_orderdata
orderdatax = wk_orderdatax
     IMPORTING
return         = bapi_return.
First order change works right, but the second order generate the error:
TYPE: E
ID      : CO
NUMBER : 888
MESSAGE: Internal: Error when reading document table RESB
The error is generated by COXT_BAPI_ORDER_CHANGE , called internally from the above BAPI_PRODORD_CHANGE
And I have to exit from my custom report and reprocess the second order to work.
It seems that there is a lock on RESB table.
Could you
help me?
Thanks a lot
Giancarlo

You need to find the lock that is being set. After your BAPI Commit, you need to test that the lock is cleared. If not, do a wait for 1 sec and retest.
Unlock (and lock) are queued objects that do not occur until after the commit is complete. Because they are queued, they can get slow. Especially when a background process is going to try to work with multiple in a short period of time.

Dont find purchasing document and item in RESB table

Hi Guys,
**I have a requirement to find production order for puchase document and item and get product cost, for this i am trying to find the link between purchase docuemnt and production order (other than material) and i found RESB table but some how i dont find Purchase document information in that table the feild is blank , could anybody pls let me know how can i ahcieve this??
And i found one datasource for this 2lis_02_ACC but that is pulling only when purchase document account assignment happend and i dont find my required values from that source also.
Thanks,
chandra.

This is a case where I would go to the MM or PP functional consultant on the project, or the end customer, to determine how they would manually connect the dots to get from the purchase order to the production order.
There are ways on going about this, but it depends on the configuration of your R3/ECC source environment and at what point the data is required. For instance, you might be able to go from:
EKKN-EBELN = BSIK-EBELN
EKKN-EBELP = BSIK-EBELP
BSIK-AUFNR = AFKO-AUFNR
This would be after account assignment.

Regarding RESB table changes

Hi..
I m working on one interface, in which i hav RESB extraction process. For the initial run of this interface all the records should be downloaded .But on subsequent execution i need only the changed records. The problem is there is no means for me to keep track of the changes in RESB, as these are not getting reflected in change tables CDHDR and CDPOS. Also there is no CREATED/CHANGED date fields in RESB table. Does anyone know any alternative for fetching the changed or newly records from RESB table based on date?

Hi Cynthia,
In the runtime we can check for the changes that are made in a table by using the mirror tables. there would be XRESB and YRESB tables in runtime which would hold the mirror images of the table contents before change and after change. so we have to perform a check of the fields from both the table at runtime. If there is a change perform the required action accordingly.

It depends on your SAP release. The easiest way to see if it's possible is to go to OSS and type 'GLPCA performance'. There are several notes regarding this issue, but only some could be reolevant for your current SAP release.

I want to get data from only RESB table without loss of any deltas

i have to fetch the reservation details for the production orders.
we are using descrete manufacturing method to keep track the Work in process and cost .
for addition of components manually in the production order we can track thru change date i.e From AUFK table with field name AEDAT. for each time when we are adding the components the system will create a new line item In tableRESB-OBJNR(field)
i need very few fields from RESB table to be pulled into SAP BW.
how should i proceed creating a generic exractor without any loss of deltas.
i want to get data from only resb table into sap bw.
how should i proceed with Generice extractor with single table RESB and what would be the delta field . could any one throw some light .
all answers would be rewarded with points

I have few reports for BOM data is to be pull into bw
all the reports contain the same tables Mentione below
MAST- material to BOM LINK
STKO- BOM header
STPO- BOM ITEM
STAS- BOM ITEM SELECTION
how should i create ageneric datsource satisfying that all the data comes from these tables without fail of deltas,
my doubts.1. Do i have to create a separate data sources (generic) for all these individually and load into separate ODS'S AND CLUB THEM into single ODS further.?
if i create i dont know what should be delta field that has to be picked for each datasource
2. Do i have to create a view on all these tables and create a generic datasource.if created what would be the delta field i have to select.
could you pls let me know how should i pull the data without loosing any deltas
could you pls let me know the flow with delta fields mentioned

P

Performance issue with RESB table

Hi,
User want to improve the performance of a standard program RLLL07SE in which a RESB table data is fetched and take much time on it.
The select querry for RESB is,
    SELECT * FROM RESB WHERE
           MATNR = MATNR AND
           WERKS = WERKS AND
           XLOEK = SPACE AND                    "Löschkennzeichen
           KZEAR = SPACE AND                    "endausgefaßt
         XWAOK = CON_X AND                    "Warenausgang erlaubt
           LGNUM = LGNUM AND
           LGTYP = LGTYP AND
           LGPLA = LGPLA.
whereas the table index is created on following fields of RESB,
MATNR
WERKS
XLOEK
KZEAR
BDTER
What possible can be done in this respect as the program is a standard one we can change only in Table Inxex I guess..or what else can be done?
Can we add LGNUM LGTYP LGPLA into the particular index apart from the existing fields?

Hi,
Instead of creating the Index, Get Data from RESB with the where clause having the entire key of the index and then loop to the internal and delete the unwanted entries as shown below.
loop at itab.
if itab-LGNUM = LGNUM AND
    itab-LGTYP = LGTYP AND
    itabLGPLA.
else.
     delete itab index sy-tabix.
endif.
endloop.
As u r getting data with entire index fields the performance will surely increase. Also avoid Select * and retrieve whatever fields u require.
As you r not having value to the field BDTER, you can pass a range or select-options for this field which has empty valuee.

Satya

Purhcase order is archived and reservatins are still open in RESB table

Hi Experts,
The purchase order has been archived and reservations to this order is still open in table RESB - KZEAR. There is no reservations display in MD04. The mateial is in subcontracting scenario.
We can clear this reservation technically by updating the table in pre-production. But the problem arised in production environment. We cannot do any technical changes.
My question is: How can we clear these reservations functionally??
Pl give your valueable suggestions.
Best answers will be rewarded.
Regards,
Surya.

Hi
The final issue indicator in RESB table is shown as blank. If we select 'x' Indicates that a reservation item is completed.
How can we get functionally the indictor is to be 'x' as the PO is archived?
Thanks & Regards,

Access resb table

How can I access RESB table from EKPO table ?? Thanks

Hi Jennifer,
From EKPO, i thing that you'll get the material and plant, then you search it in RESB table, but it might be more then 1 reservation, so you need to add logic to get the requirement date, either you get the min or max date.
Reward points if useful.

RESB table about delete flag

dear experts
issue: A is FG, B is purchase part, is component for A, when creat independent requirement, MD02 run MRP, plan order is generated for A, when change this planned order's component B to C, then A transfer dependent requirement to C. then cancel indenpendent requirenment for A, then run MRP, the planned order for A is deleted and missed. but the dependent requirement to C is not missed, i found the TABLE-RESB for material C is also exist, the delete flag is not set automatically. so meet this dependent requirement, sysyem will generate PR.
the origin requirement for A was deleted, why dependent requirement still exist in MD04?
bset regards
lee

Dear Lee,
You need to run MRP with planning mode as 3 ( Delete are re create planning data )
Then system will automatically deletes the depended requirements
or use MD16 for deletion
