The following steps can be used to upload mappings via the .txt files.
1) Check which instruments and datasets have been mappedThe main Instrument page and the main Datasets page displays the number of questions mapped to variables. Those without a number, need to be mapped.2) Import the sledgehammer xml
Admin > Import. Under Upload DDI Dataset files, browse and Import Dataset. This might take a while to appear in the Datasets list. Note that the prefix used when running Sledgehammer must be identical to the instrument prefix. This must be checked carefully as otherwise this will mean mappings will have to be redone.
32) Import the variable mappings
Admin > Datasets > search for the loaded dataset (prefix or dataset name) > Import Mappings. Both the tvlinking.txt and the dv.txt can be imported. If uploading more mapping files, these will not replace those already mapped, but will add any additional mappings.
43) Import the question mappings
Admin > Instruments > search for the questionnaire prefix > Import Mappings. Both the qvmapping.txt and tqlinking.txt can be imported. If uploading more mapping files, these will not replace those already mapped, but will add any additional mappings.
54) Check the mappings in both the dataset and instrument view.
