In our projects we might have faced the situation where we have to upload the data trough file system (flat file), for uploading data to data target we need to create data source, data target, transformation and DTP manually, for simplifying the creation of dataflow process a new wizard tool introduced in SAP BW 7.3.
By using dataflow wizard tool we can create a entire dataflow with existing/new objects, also dataflow templates can created with SAP delivered pre-defined dataflow template, this tool reduce the considerable amount of time for creation of data model .
Steps to create flat file data upload data flow trough wizard tool
Use Tcode- RSA1
Click on Wizard tool icon
Click on continue
Specify the file path in the wizard initial screen (Flat file Path) check below
Give a technical name of the data source(For creating New datasource for uploading data from flat file),
Description of the data source,
Specify the file system name and
Type of data source (Transaction, master data attribute and text) then click on continue
Specify the attribute values for Data source like data separaters etc...
Click on continue then it will take you to next level of wizard selection
Now we can see the datatarget area, here we have to specify type of infoprovider like DSO,InfoObject,Cube..etc..then subtype for Infoproviders ( Standared/writeoptimized for DSO,Attribute/text for InfoObject etc...)then give technical name and description of the infoprovider (can also create new data target)
After providing infoprovider details then click on continue
Next step :Field assignment
In this step we can assign(map) existing Infoobjects to specified fields, also we can create new IinfoObject by clicking New InfoObjects icon in the field assignment of wizardtool .
You need to specify field type like Primary characteristic/Display attribute/ Compounded characteristic/Navigation Attribute for IinfoObjects,Key fields and data fields for DSO,refer below screen
Click on continue then it will take you to final step
Before clicking finish icon you can check the information about generated/created objects like transformation and DTP then click on finish .
Restart the transaction RSA1, now you can see a new dataflow under infoprovider segment
With new dataflow wizard tool we can create entaire data flow model with less effort, hence we can save time and it’s very simple to perform.
Also we can use wizard tool to create data flow for existing data source (like ECC /CRM) to data target .
