LDCHTKT is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "Screen fields for changing no. of takts/capacities" Information within sap ABAP programs. This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately. i.e. DATA: wa_LDCHTKT TYPE LDCHTKT.
The LDCHTKT table consists of various fields, each holding specific information or linking keys about Screen fields for changing no. of takts/capacities data available in SAP. These include WERKS (Plant), LNSID_TXT (Line segment description), LTYPE (Work center category of the line segment), TAKTS (Number of takts)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
