Logistics Extractors Data Flow from LBWQ or SMQ1 to RSA7 in ECC and Delta Extraction inBI

Purpose

The purpose of this document is to explain the data f low process from ECC to BI/BW, talking about LBWQ - Logistics Queue Overview , it’s relation to SMQ1 – Outbound Queue, and RSA7 - BW Delta Queue

Monitor and Data Loads in BI/BW.

Overview

After reading this article, you w ill know the concepts and how the data/records w ill transfer from one layer to another layer and f inally how it w ill f low into the BI/BW system using Delta Loads.

Concepts

SMQ1: qRFC Monitor for the outbound queue, w e use this transaction to monitor the status of the LUWs in the outbound queue and restart any hanging queues manually.

LBWQ: This is a transaction that does nothing but calling SMQ1 for queues ‘MCEX*’ skipping the selection screen.

RSA7: BW Delta Queue Monitor, w e use this to see transferred data (delta) for a DataSource and a Target system.

LBWE: LO Data Extraction: Customizing Cockpit. Here w e can activate/deactivate extraction, maintain extract structures and change update mode for each logistics application.

Live Scenario – Enabling queued delta

We w ant to know how the qRFC Monitor for the outbound queue (SMQ1) and BW Delta Queue (RSA7) w ork for delta records. In this example w e w ill use DataSource “2LIS_03_BF” (and 2LIS_03_UM). We

assume that Init loads w ere already executed for the extractors and w e are ready to go for delta loads in BW.

First, w e set the relevant application’s Update mode to ‘Queued Delta’. See the below screen.

Go to LBWE and set Update Mode to ‘Queued Delta’:

Check outbound queue

If there are already posted or changed documents related to Inventory Controlling – Application 03, they w ill appear in the outbound queue LBWQ, as can be seen in the screenshot below .

If there are no posted/changed documents, you can post or change any, just to create an entry in LBWQ. This can be done in transaction MB1C for example.

Check BW Delta queue

Now check transaction RSA7 – BW Delta queue Monitor.

Here w e can see number 2 under ‘Total’ in the delta queue:

To see the entries select the DataSource and click on Display data entries Icon.

Select Delta Update and execute.

Nothing is show n here, despite there w ere 2 records under ‘Total’ in RSA7 initial screen.

Now select ‘Delta repetition’ in the ‘Display data entries’ screen and execute:

You can see 408 entries in Delta Repetition.

Run the V3 update job

Now , run the V3 job from LBWE, to send the documents from the outbound queue to the delta queue. Don’t forget to set the job to run immediately.

You can f ind the “New Job is Scheduled” on the status bar, so our V3 is started.

Check if the job finished successfully

The job should end shortly. You can f ind its status in SM37, w ith job name “LIS-BW*”:

See the job status, it is f inished.

Check outbound queue again

Now let’s go back to LBWQ and see the queue. Notice that w e can’t f ind MCEX03, because after executing V3 job, all data records moved from Outbound queue to Delta queue, that is, from LBWQ to RSA7.

Check BW Delta queue again

In RSA7, w e can see that the Total has increased from 2 to 3. Now display the entries for the extractor in question.

In the update mode, select Delta update and execute:

Now w e can see 99 records, w here before it w as 0:

Come back and select Delta Repetition and execute.

Here you can f ind totally 507 records. How ? Earlier w e have 408 records, now 99 records after V3 job, so totally 507 records.

Now go to BI/BW System and execute DELTA Info Package for 2LIS_03_BF DataSource.

You can see 99 records in PSA. See the below screen.
