Once the correct values are entered click the OK button to <br />post the changes back to the Lag/Loss Editor dialog. <br /> <br />8.2.5 Saving Lag/Loss Data <br /> <br />To save the current laglloss values to the SPWRMS database click on <br />the Save Current bunon. Values are saved under the current date, <br />and only one set is saved each day for all SPWRMS users. For that <br />reason, the user must be cautious when saving lag/loss data to the <br />database. When a save is performed, any data saved earlier in the day <br />is overwritten, including data which may have been saved to the data- <br />base since the current values were loaded. It is also possible (and <br />undesirable) to save the default values to the database as though they <br />were a different set of current values. <br /> <br />It is imponant to note that it is not necessary to save the current lag! <br />loss values to the database in order to use them to perform a curtail- <br />ment or relaxation analysis. The user may load current values from <br />previous days. modify them, and use them for curtailment and relax- <br />ation analyses without performing a save. The current values hold for <br />all analyses whether saved to the database or not. <br /> <br />8.2.6 Resetting Lag/Loss to Defaults <br /> <br />To use the default set of laglloss values instead of the current values, <br />reset the current values to the defaults by clicking on the Reset to <br />Defaults button. This action causes the current values to be equal to <br />the default values for the purposes of cunailment and relaxation anal- <br />ysis. <br /> <br />8.2.7 Closing the Lag/Loss Editor <br /> <br />Click on the Close button to remove the Lag/Loss Editor dialog. All <br />lag and loss data displayed as current values when the Lag/Loss Edi- <br />tor is closed will be used for any subsequent cunailment and relax- <br />ation analyses. <br /> <br />45 <br /> <br />7/31/94 <br />
