Producing a Message to Kafka via a TCP ABAP Push Channel

In exploring options for moving data/events around our landscape we wanted to know if it would be possible to have a native ABAP TCP Kafka client.  One could of course consume one of the REST Proxy options (eg. Confluent’s), which would be a much simpler option than building a TCP based client from scratch, but we still wanted to know if it would be possible.

How to implement Link to action in ABAP webdynpro ALV

If you include the standard webdynpro ALV component SALV_WD_TABLE into your own component, you could not directly change the ALV table column as usual. In ABAP Webdynpro an example of link to action element used in ALV looks like below.

Using Conditional Aggregation in CDS views on AnyDB or HANA

Background:


We recently needed to quickly create an extract of sales order related data with ~200 columns using ~20 source tables from ECC on anyDB. With a relatively straightforward pull of data, with little or no calculated columns or complex transformations but a short timeline, we decided to use CDS views to exclusively gather the data.

OpenXML in word processing – Custom XML part – mapping flat data

In my first blog I wrote short introduction about OpenXML in word processing and how we can work with word documents in ABAP. In this blog I will describe custom xml part of word document and give some examples how we can use it in ABAP. For example how custom data can be used in on demand printing requests to provide customer data in document with content control.

Custom XML parts were introduced in Microsoft word 2007 along with Open XML formats. Custom part of microsoft word document is used to store custom data and it is not suprising that data format is XML. In connection to Custom XML we will use also Content Control functionality of Microsoft Word. Custom Control is set of individual objects to control and customize content of the document. One of its purpose is to map data from different sources (in our example from custom XML) to exact place in word document. So let’s go with example.
