SAP QM Optional Characteristics check in TABLE PLMK
Hi Team,
In this Blog, we will see how to check optional characteristics for inspection plan in Table : PLMK.
As, Characteristic Control Indicator in Table is shown based on Logic we will check in this Blog the Logic for Optional Characteristics for inspection plan in this Blog.
Below attached is screenshot of Inspection Plan with Characteristic Control Indicators selected as optional characteristics.
Below is screenshot of TABLE : MAPL.
Here we get Inspection Plan Group against Material.
Here we give Input Group which we get at Table: MAPL against Material, Plant.
Control ind: Characteristic column shows whether Master insp.charac. assigned for a material is in optional characteristics based on below logic explained in Table.
| Character position | Meaning | Values |
| 1 | Quant or Qual charac | X is quant, Null is Qual. |
| 2 | Record measured Values | X or Null, (set to null if 1 is qual) |
| 3 | Characteristic Attributes | X or Null |
| 4 | Upper Spec | X or Null |
| 5 | Lower Spec | X or Null |
| 6 | Target Value | X or Null |
| 7 | Scope | = is Fixed, > is Larger, < is smaller, Null is No Scope** |
| 8 | Long term inspection | X or Null |
| 9 | Recording type | + is individual, null is summarized, – is no recording, * is classed recording |
| 10 | Documentation | Null is no documentation |
| . (period) is doc required if rejected | ||
| + is doc required | ||
| 11 | Charac. req. or not | X is required, Null is optional, + is after acceptance, – is after rejection |
| 12* | Synchronization is Active | X or Null |
| 13 | Additive charac. | X or Null |
| 14 | Destructive charac. | X or Null |
| 15 | Formula | Null is no formula, X is calculated chara, 1 is input processing |
| 16 | Sampling proc. Required | X or Null |
| 17 | Scrap Share/Q score | X or Null |
| 18* | Fixed | X or Null – Ctrl indicators can not be changed |
| 19* | Record # defects | X or Null – Allows recording of # of defects in addition to # of nonconforming units |
| 20* | Subsystem | X or Null – For control stations – Not QM relevant |
| 21* | Specifications | X or Null – Can Change specs |
| 22 | Test Equipment | X or Null |
| 23 | Defects recording | X or Null |
| 24 | RR Change Docs | X or Null |
| 25 | SPC charac. | X or Null |
| 26 | Null is print, X – Do no print, * is do not print at skip | |
| 27* | Parameter Characteristic | X or Null – Can be used as a Parameter characteristic |
| 28* | Process Characteristic | X or Null – Characteristic of a the process |
| 29 | UNKNOWN | |
| 30 | UNKNOWN |
Based on Table Logic character position 11 if it is Null then it is Optional Characteristics
Output in PLMK Table is
| XX XX = + X X |
If we break it into character position wise we get as below,
| Character position | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 |
| Control ind: Characteristic | X | X | X | X | = | + | X | X |
Summary: –
With the help of this blog, we can understand Characteristic Control Indicator Logic in Table

You can simply overlay the field PLMK-STEUERKZ with the structure QMKST to read the control key parameters. Just move PLMK-STEUERKZ to a variable of type QMKST.
