Start with the RSA datasource

Rsa2: OLTP metadata repository (ECC end) This T-code can be used to find the complete datasource information, so that it will not be in the maintain generic datasource (T-CODE: rs02) dead-end press enter, no response without knowing the reason. Because datasource may obtain data through function, you can obtain the extraction method through the Extraction Methods Field. Rsa3: extractor checker(ECC end)

The data source extraction test can play a certain role in verifying the consistency between BW and R/3 data, especially in testing whether the original data has obvious timeliness effect. Personally, I was quite impressed with the debug mode. When I used to extract Copa data, it was clear that the table data was available, but it could not be extracted. By selecting the debug mode, it is found that the data is processed during the original extraction process. If the value field is empty, this record is ignored. In reality, Copa adds some columns. Based on the features of the Copa table, the values are only placed in these new columns, resulting in data extraction failure. Then, the table is rebuilt through keb0 and the new column is selected to solve the problem. Note: The filter condition is displayed only when you enter datasource and press Enter. Rsa5: Install business content

When datasource is used for the first time, it may be found that the test fails in rsa3, probably because no related activation is performed. Therefore, you must use rsa5 to activate datasource. Rsa6: maintain datasources

There are many things that can be done here. For example, we often encounter the problem of adding conditions to datasource or hiding a column to enhance the data source. Rsa7: bw Delta queue Monitor Here we can see that Delta extraction is currently in progress. If the extraction method is full, it will not appear here. We can also obtain several pieces of information. The first Delta is related to the target system, and the second datasource has only one Delta queue for a target system. The third target system is BW system, which corresponds to RFC destination. As for how to maintain RFC destination, even if you replace the host halfway, of course, changing the host will affect the data extraction continuity. This is not allowed, and similar errors have also occurred before. The fourth total is the data batch instead of the specific number of records. Although the number is 1, the number of records may be 100 when the data is extracted. Don't be surprised,
It is like a data packet and a data packet for storage, and the several records we want do not have a direct relationship, is to display the data packet of the last delta.

There is a special mark in 1_co_pa_2006 and 1_co_pa_2005 In the Stat Field. Here we record that the Delta method operates through the Time Label and you can click. Current status is the last extraction time. Rsa8: datasource Repository The interface is the same as rsa6. We can see from se93 that they are actually the same. Rsa9: Transfer Application Components Activating the standard system structure makes it much easier to search for datasource.
