Hi Gero,
MEASURE (already pre-defined as l/h) is one of the four additional columns only used for relevant application. This column is only used if height (standing up) or length (lying down) of children aged above 2 and less than 2 respectively are taken against the protocol.
If a child’s length is supposed to be taken (ex. 20m) and height is recorded instead, under the MEASURE column, letter ‘h’ (Height) is entered and letter ‘l’ (Length) if vice versa.These entries enable ENA software to apply a correction factor for determination of the nutritional status of such cases correctly.
You could also consult the ENA manual for more details on application of the other 3 additional columns from the Complementary Tools and Resources https://smartmethodology.org/survey-planning-tools/smart-capacity-building-toolbox/
